    Sharing an internal tool that accelerated my development work 10-fold, especially with API debugging. Thought fellow developers here might find it useful. As a developer, I often have trouble reproducing errors at the client end. https://intercept.rest lets me debug and monitor API requests and responses. It is similar to the Network tab in Chrome Developer Tools but works for any API: mobile apps, webhooks, frontend etc. After I shared it with a close circle of friends, they found it incredibly useful and even found new use cases, I never imagined.

    G’day Hacker News, I’m Simon Gurcke, the sole founder of Apitally (https://apitally.io). I’m building a simple API monitoring and analytics tool for Python / Node.js apps. It helps users understand API usage and performance, spot issues early and troubleshoot effectively when something goes wrong. Features include: - Dashboards: Provide insights into API traffic, errors, performance and consumers. - Request logging: Opt-in and highly configurable in terms of what data is logged. Users can drill down from aggregated metrics to individual requests (proven to be super helpful…
